Master unifies every live agent with its exact SessionId and moves declarative startup failures to agent-loop/config-start-failed. Keeping the branch’s AgentId label binding would let the TUI target the wrong lifecycle after reload and would miss asynchronous resume failures. Resolve that contract migration by giving the selected terminal front door the same generated or resumed SessionId as agent-core, mounting the front door first, and entering fullscreen only after the matching root appears. Refresh the source-derived catalogs and keyless terminal goldens so Code Mode, workflow, Cordis-tool, and transient UI scenarios all exercise the merged identity model.
tui-agent
The full-screen terminal counterpart to the coding-agent readline REPL and acp-agent server. It reuses the coding agent's backends and tool composition, then fixes the shared terminal app to the dsh-tui front door.
Run it
pnpm run demo:tui
The command needs DEEPSEEK_API_KEY in the environment or the gitignored repository-root .env. Set RESUME_SESSION_ID to reopen a persisted conversation under ./.sessions.
The TUI renders Markdown history, reasoning, tool-owned terminal/diff/generic cards, token totals, and the latest todo list. Enter submits or steers while the agent is running; Ctrl+O expands cards, Ctrl+R toggles reasoning, Escape cancels, and /help lists commands. ask_user_question opens a keyboard-driven overlay.
Run pnpm run demo:code-mode tui for the sibling Code Mode overlay.
Composition
cordis.yml includes the readline coding-agent leaf so the LLM, bash, filesystem, compaction, subagent, workflow, todo, timeout, and spill choices have one owner. Its asserted patch replaces only the terminal app config and forces ui.mode: tui; code-mode.cordis.yml applies the same front-door patch to the coding agent's Code Mode overlay.
Snapshot tests
tests/snapshots/<scenario>/session.jsonl supplies recorded user prompts and model chunks; sibling child logs drive subagents and workflows. The keyless suite executes those scripts through the real loop and tool implementations, then compares readable terminal cell/style goldens. Use pnpm run test:snapshot:refresh for presentation-only changes and pnpm run test:snapshot:record with a DeepSeek key when a recorded model journey changes. The implemented TUI snapshot RFC owns the scenario matrix and the split between recorded journeys, transient package snapshots, and PTY coverage.
